“…The values of CTR obtained on the VD and DV views of the African grasscutter from this study did not differ significantly, irrespective of age. Sak and Pazvant (2021) made similar observation in the Persian cats. There are divergent views as to the preferred radiographic projection for cardiac mensuration; Buchanan (2000) advocates the preferred use of DV projections in dogs because cardiac contours are more consistent and the heart is magnified in VD radiographs due to the varied distance between the heart and the radiographic cassette.…”

“…Conversely, Van Den Broek and Darke (1987) preferred VD to DV views for determination of CTR in cats. The present study and that of Sak and Pazvant (2021) have shown that either view can be applied for the establishment of CTR in animals.…”

“…In the present study, there was no significant difference in the radiographic values of VHS between opposite projections in both the juvenile and adult African grasscutters. Ukaha et al (2013), Ulum and Noviana (2018), Puccinelli et al (2021) Sak and Pazvant (2021) and De Silva et al (2022) made similar observation in the adult west African dwarf goats, laboratory mice, Chihuahua dog, Persian cats and guinea pigs, respectively. Conversely, Birks et al (2017) and Luciani et al (2021) observed that the VHS was significantly higher on the RtL than the LeL projections in the dachshund and Australian cattle dog breeds, respectively.…”

“…Dennis et al (2010) opined that increased diagnostic yield and accuracy of cardio-thoracic radiographic appraisals is achieved by the use of these four thoracic radiographic projections. Some of the radiographic indices that depict the size of cardiac silhouette include the cardio-clavicular ratio (Gardner et al, 2007), cardiac long axis-thoracic height ratio (Diniz et al, 2013), vertebral heart score (VHS) (Luciani et al, 2019), vertebral left atrial size (Puccinelli et al, 2021), cardio-thoracic ratio (CTR) (Sak and Pazvant, 2021), aorticocardiac ratio (Ukaha et al, 2002) and cardiac axis ratio (CAR) (Ukaha et al, 2002). However, CTR, VHS and CAR are of interest in the present study.…”

This research aimed to establish reference radiographic indices for future cardio-thoracic appraisals in the African grasscutter. Twenty healthy animals consisting of equal number of juveniles and adults were used. Forty thoracic projections consisting of dorsoventral (DV), ventrodorsal (VD), right lateral (RtL) and left lateral (LeL) views were acquired. The evaluated parameters included thoracic and cardiac diameters on the DV/VD radiographs, and cardiac long and short axes on the RtL/LeL radiographs. Cardiac indices generated were cardiothoracic ratio (CTR), vertebral heart score (VHS) and cardiac axis ratio (CAR). The reference values of CTR on VD and DV were 0.52 ± 0.02 and 0.50 ± 0.02, respectively. The difference was not significant (P > 0.05). The mean radiographic values of CTR for juvenile and adults on DV were 0.48 ± 0.04 and 0.52 ±.0.01, respectively. The reference values of VHS on RtL and LeL were 8.70 ± 0.23 and 8.60 ± 0.21, respectively. The difference was not significant (P > 0.05). The mean values of VHS for juveniles and adults on RtL were 8.20 ± 0.30 and 9.20 ± 0.12, respectively. The difference was not significant (P > 0.05). These indices are relevant in future diagnosis of cardiac diseases in the African grasscutter.

“…It has been reported that radiography is a reliable diagnostic tool to identify cardiomegaly in birds (8). For this purpose, researchers have focused on the reference ranges for the heart width, the measurement used in humans and domestic animals (dogs and cats) (4,5,19). In subsequent studies, these reference values were obtained for many bird species (6,12,15,16,20).…”

Physical examination of the cardiovascular system in birds is quite difficult compared to other animals. As in humans and mammalian animals, radiography is a reliable diagnostic tool to identify cardiovascular disorders in birds. However, cardiovascular radiography studies for birds are very limited and reference information is lacking. In this study the aim was to determine the reference values of cardiac radiographic measurements that can be used especially in the diagnosis of cardiomegaly in storks, which is a free-living bird species. For this purpose, 26 white storks without cardiovascular disorders were used in the study. Radiographs were taken in lateral and ventrodorsal projections. Five measurements: heart length (61.70 ± 6.69 mm), heart width (51.65 ± 4.84), carina length (139.80 ± 10.05), thoracic width (87.45 ± 6.58), and coracoid width (10.24 ± 1.20) were performed. The ratio of the heart width to thoracic width was 59.16%. The ratio of heart length to carina length was 44.28%. Heart width correlates significantly and positively with the thoracic width (R: 0.556, R2: 0.310, P: 0.003). The heart width can be estimated by using the thoracic width values with the regressionbased formula in the results of this study. Clinically, it can be determined whether an individual case falls between the minimum or maximum reference values for heart width or length. The results presented in this study may provide clinicians with reference information regarding cardiomegaly.

This study was conducted to produce a three-dimensional model of the thorax and lower respiratory tract in Van cats, to reveal their morphometric properties, and to investigate the anatomical structure of this region in more detail. A total of 16 adult Van cats (8 males and 8 females) were used in the study. The thoracic region of the cats was scanned using multi-detector computed tomography device. The images of the scanned region were transferred to the MIMICS 20.1 software that creates three-dimensional reconstruction in order to produce the models. The morphometric measurements were obtained from these models and the index values were calculated. When the data were analysed in terms of sexual dimorphism, significant differences were determined between the sexes in terms of transverse diameter of the thoracic cavity in apertura thoracis cranialis (T2) (P < 0.05), minimum width of apertura thoracis cranialis (T3), and height of the thoracic cavity in thoracis cranialis (H1) (P < 0.01). The index values of the data revealed a significant difference between the sexes only in terms of the thoracic index 2 (P < 0.05). The 7th sternebra was shorter and more flattened than the other sternebrae in Van cats. In conclusion, three-dimensional models of the thorax and lower respiratory tracts of Van cats were produced in the study. It is thought that the data of the study may be useful in clinical practice and academic studies in the field of veterinary medicine.
